Mark 1:27
The people were all so amazed that they asked each other, what is this? A new teaching — and with authority! He even gives orders to impure spirits and they obey him — the crowd combines the amazement at the teaching with the amazement at the exorcism under the same category: authority. A new teaching is not merely novel but unprecedented — the combination of teaching and commanding authority over the spiritual realm is genuinely new in their experience. He even gives orders to impure spirits and they obey him: the obedience of the spirits is the key datum. Other exorcists used elaborate formulae and rituals; Jesus commands, and the spirits obey. The authority is in the person, not the technique.
